Penetration testers get paid to hack into systems, legally. Organizations hire them to find security weaknesses before real attackers do, then explain exactly how to fix them. It is one of the most sought-after roles in cybersecurity, and one of the most rewarding for people who love solving puzzles.
If you want to know how to become a penetration tester, this guide covers what the job involves, the technical and soft skills you need, the certifications employers look for, typical salary ranges, and a step-by-step path from beginner to professional pen tester.
A penetration tester, often called a pen tester or ethical hacker, is a cybersecurity professional who simulates real-world cyberattacks against an organization’s networks, applications, and people. The goal is to uncover vulnerabilities that a malicious hacker could exploit.
Unlike criminals, penetration testers work with written permission and a clearly defined scope. Every test ends with a report that documents what was found, how serious each issue is, and how to remediate it.
Penetration testing sits on the offensive side of security, often called the “red team.” Defensive professionals, such as SOC analysts and incident responders, make up the “blue team.” Both sides work toward the same goal: keeping attackers out. For example, a pen tester might prove that a phishing email and a weak password could give an attacker the foothold needed to launch a ransomware attack, long before a real criminal tries it.
Day-to-day responsibilities vary by employer, but most penetration testers spend their time on tasks like these:
Many pen testers specialize over time. Common areas include:
Penetration testing requires a broad technical foundation. You do not need to master everything at once, but strong fundamentals make every later step easier.
Strong soft skills for IT professionals often separate good pen testers from great ones.
Certifications validate your skills to employers and are often listed as requirements in job postings. Here are the most common penetration testing certifications, roughly in the order many professionals earn them.
Network+ builds the networking knowledge every pen tester relies on. It is an ideal starting point if you are new to IT. Learn more about Network+ certification or the CompTIA Network+ Bootcamp.
Security+ is the most widely recognized entry-level cybersecurity certification and a common baseline for security roles, including Department of Defense positions. Explore Security+ certification and the CompTIA Security+ Bootcamp.
PenTest+ is built specifically for penetration testers. It covers planning and scoping, reconnaissance, vulnerability scanning, attacks and exploits, and reporting. It is vendor-neutral and includes performance-based questions that test hands-on skill. See PenTest+ certification and the 5-day CompTIA PenTest+ Bootcamp.
CEH is a well-known ethical hacking certification, especially in government and defense hiring. Learn more about CEH certification and how CEH holders contribute in our article on the role of ethical hackers in federal cybersecurity.
As your career grows, certifications such as CompTIA CySA+ (certification and bootcamp) help you understand the defender’s perspective, while CISSP (certification and bootcamp) supports a move into security leadership.
For a broader comparison, see our list of the best cybersecurity certifications for beginners and tips for passing your certification exam. CIAT students also benefit from an Unlimited Certification Exam Retake Policy that covers all CompTIA certifications, including Network+, Security+, and PenTest+. The policy excludes CISSP and EC-Council CEH.
Penetration testing is a well-paid specialty, and pay rises quickly with experience and seniority. According to Salary.com, the average U.S. penetration tester salary is about $88,571 per year as of September 2026, with most earning between roughly $73,000 and $100,600. Senior and leadership roles earn significantly more.
| Role Level | Average Annual Salary (U.S.) |
| Junior Penetration Tester | $67,303 |
| Penetration Tester I | $84,529 |
| Penetration Tester II | $101,753 |
| Penetration Tester III | $130,481 |
| Penetration Tester IV | $149,975 |
| Penetration Tester V | $174,299 |
| Penetration and Vulnerability Director | $208,300 |
Salary depends on experience, certifications, specialization, industry, and whether a role requires a federal security clearance. To learn what else affects pay, read about the factors that impact IT starting salaries.

There is no single path into penetration testing, but most successful pen testers follow a similar progression.
Penetration testers need to understand how systems work before they can break them. Many start in help desk, desktop support, or networking roles. A certification like CompTIA A+ (certification and bootcamp) or Network+ is a strong first step. If you are switching careers, our career change to tech guide can help you plan.
Next, build a solid understanding of security concepts: threats, vulnerabilities, cryptography, access control, and common attack techniques. Earning Security+ at this stage validates your knowledge and opens doors to entry-level security jobs.
A formal program in cybersecurity gives you structured learning, hands-on labs, and credentials that many employers require. Programs that bundle industry certifications into coursework let you earn both at the same time. Read more about choosing the right cybersecurity degree and whether a cybersecurity certificate vs. degree fits your goals.
Hands-on practice is essential. Build a home lab with virtual machines, practice on intentionally vulnerable applications, and use legal training platforms that offer realistic hacking challenges. CIAT students can sharpen these skills with hands-on lab kits and through the Cybersecurity Club. Never test systems you do not have written permission to test.
Once you have practical skills, pursue a pen testing certification like CompTIA PenTest+. It demonstrates to employers that you understand the full testing process, from scoping to reporting.
Few people land a senior pen testing job as their first security role. Common stepping stones include SOC analyst, vulnerability analyst, security analyst, and junior penetration tester positions. Explore entry-level cybersecurity roles to see where you might start.
Document your lab work, write-ups, and projects to show employers what you can do. Our guide to building a professional IT portfolio while still in school offers practical tips. When you are ready, review how to apply for a job in cybersecurity and learn what cybersecurity employers look for.
Penetration testing offers plenty of room to grow. A typical progression looks like this:
Some pen testers later move into security architecture, application security, consulting, or broader leadership roles. To see how offensive skills fit into the bigger picture, read about how to develop a successful career in the cybersecurity field.
Becoming a penetration tester takes the right mix of fundamentals, hands-on practice, and recognized certifications. CIAT’s cybersecurity programs cover ethical hacking and penetration testing techniques, along with networking, cloud security, and incident response, with industry certifications built into your coursework.

Most people need two to four years to move from beginner to penetration tester, depending on their starting point. Those with prior IT or networking experience can move faster, especially if they earn certifications like Security+ and PenTest+ along the way.
A degree is not always required, but many employers prefer or require one, especially for government and enterprise roles. A cybersecurity degree or certificate combined with industry certifications gives you a strong advantage when applying.
It is difficult to start directly as a pen tester with no experience. Most people begin in IT support, networking, or a SOC role, then transition into penetration testing after building skills, certifications, and a portfolio of hands-on work.
CompTIA PenTest+ is a strong first pen testing certification because it covers the full testing process and is vendor-neutral. Many beginners earn Security+ first to build a security foundation.
The terms are often used interchangeably. Ethical hacking is the broader practice of legally testing systems for weaknesses, while penetration testing usually refers to a structured, scoped engagement that ends in a formal report.
Python is the most useful language for pen testers because it is widely used for scripting and automation. Bash and PowerShell are also important, and knowledge of JavaScript and SQL helps with web application testing.
According to Salary.com, the average U.S. penetration tester earns about $88,571 per year, while senior-level pen testers can earn $130,000 to $175,000 and directors can earn over $200,000.
Yes. Organizations of every size need people who can find vulnerabilities before attackers do. The work is challenging, well-paid, and offers clear paths for advancement into senior, red team, and leadership roles.
Penetration testing is legal only when performed with explicit written authorization from the system owner and within an agreed scope. Testing systems without permission is illegal, even with good intentions.
Many penetration testing engagements, especially external network, web application, and cloud tests, can be performed remotely. Some assignments, such as physical security or internal network tests, may require on-site work.
